我正在尝试将android工具栏作为操作栏实现。我的操作栏应包含一个徽标作为标题和溢出菜单。溢出菜单图标颜色为绿色。我使用了一个小部件 OverflowMenuButton 但添加此内容后会出现一些异常。我不知道如何正确使用这个小部件。
这是我的代码
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
android:background="@color/white"
android:gravity="center">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="false"
android:focusable="false"
android:longClickable="false"
android:src="@drawable/logo_multi"/>
<OverflowMenuButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@color/green"/>
</android.support.v7.widget.Toolbar>
我发布了一些错误行

在oncreate中，
setContentView(R.layout.screen_startscreen);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
